I have a standard 150g tank with dual overflows. I currently have 2 MP40ES, one on each end of the tank for flow. I have decided that it wasn't quite enough flow and I was getting "dead areas" in between the overflows on the sandbed by the rockwork. So I have borrowed a MP40W from my frag tank to put on the back wall for additional flow. However, I am not sure on what mode I should set this to and am looking for suggestions.
